No positive integer n can make 12^n a divisor of 3,176,793 simply because no EVEN can be a divisor of an ODD. Hence n is none other than 0.

Now, n^12 - 12^n = 0^12 - 12^0 = 0 - 1 = [spoiler]-1[/spoiler].

no power of an even number is odd unless until it is the zeroeth power, which is 1.

hence, n MUST be 0, giving us the value as 0^12 - 12^0 = -1.
